That's really is sad, Brian. Even if the flower buds were not damaged (which they probably are), you might not have sufficient leaves to produce ample food for them and next year. If the flower buds do make it, I'd consider cutting them off anyway, because there is a good chance they will be deformed by the cold.
As you realize, martagons tend to fair better with late frosts.
I am 3-4 weeks ahead of normal here, too. I have a few martagon noses showing, but they are all tight and not more than an inch tall. Long time regulars here know that I fall mulch my lilies way after the ground is frozen to hold in the cold. So I seldom have any worries about late frosts.
